摘要: Ricci solitons often appear as the sigularity models of the Ricci flow. The concept of linear stability
of compact Ricci solitons was first introduced and studied by Cao-Hamilton-Ilmanen. In this talk, we
investigate the linear stability of compact shrinking Ricci solitons. We will present the second variation
formula of Perelman's $\nu$-entropy for compact shrinking Ricci solitons, and prove a necessary and sufficient
condition for a compact shrinking Ricci soliton to be linearly stable in terms of the non-positivity of a
Lichnerowicz type operator related to the varational formula.
All are welcome!
